effective construction by' ..which the s oe'top or upper is properly vented or out to permit the easy insertion of the foot and the easy withdrawal of the shoe, while makin proper provision for interlocking the e ges of the vent or opening by an instantly detachable locking means so that no time is lost in releasing the vent where it is of great 1mportance to instantly strip the shoe from the foot.

It is well known that in foundries or shops where molten iron or metal is handled, in spite of all precautions, the molten metal is often dropped into the boot or shoe of the operative thereby causing serious burns and injury. in such an emergency it 1s of the utmost importance that nothing'should 1mpede the instantaneous removal of the shoe, while at the same time eficctive PI'OVlSlOll should be made for normally keepingthe shoe closed as effectively as possible agamst the inflow of such metal.

The present invention deals with this problem and consists essentially in the combination with a shoe bottom and u per whose topis slit referably on the si e to, form a vent exten ing to the to of the slice, two flaps of material next to t e vent belng provided with intermatching closing means normally held in interlocked relation by means of a locking member in the form of a flexible pin or ke or its equivalent.

This and other eatures of the invention will be set forth in the following specification and will be defined in the claims hereto annexed.

In the accompanying drawings I have shown a convenient and satisfactory con i struction and arrangement embodying the principles of this invention, in which:

Figure 1 is a side elevation of a shoe constructed in accordance with my invention, the vent being locked in closed position.

Figure 2 is a plan view of the vented side of the top or upper of vthe shoe.

Figure 3 is an enlarged detail showing out of vertica more clearly the details construction of the vent-closing and locking means; I

In the practlce of this invention according to the form illustrated, the molders shoe is of suitable and usual construction so far as the sole 1, and thehel 2, constituting the bottom, and sofar as the vamp 3 com: prlsin the forepart of the upper are concern The to portion 4 of the upper is vented, preferab y along one side from the top edge downward to or nearly to the shoe bottom.. One 'of the edge portions of the two flaps,

at the vent isiormed with an extension or tongue 6 to passinside the other fla 5 and overlap the same so as to com lete y .close the vent when the shoe is on t e foot, just as the ordinary tongue of a lace shoe-closes the vent, although the vent-closing tongue may be formed in any suitable manner. To the respective fla s 4 and 5 adjacent to the vent are secur series of intermatching metal loops 8 and-9 provided with overla ping eye portions 8, 9 which, when t e vent is closed register or align with each' other from to to bottom so as to. rmit the insertion o a suitable locking mem r or pin 7 which is preferably uite flexible, and is provided at its top wit a .knob or enlargement 7 to permit quick handling and prevent its being inserted too far to be readily gras ed and removed when occasion r uires. locking member is referab y made of raw hide or other flexib e matenal to allow the shoe top to conform closely to the contour of that adjacent to the vent.

As actually shown the loops 8 are made of wire, both arms of the loop being passed through the flap 4 adacent to the tongue portion from the outsi e and being bent and clinched to hold them in place, the clinched portions being preferably oifset or staggered alignment so as to avoid bringing the receivm The loop 9, also in this case showngas made of wire construction, may have one arm assed inside the flap 5 and the other out si e, the ends penetrating the material from opposite sides, and being clinched to prevent withdrawal. It will be understood wire s throng fromthe outside is to permit t e formation of an integral extension of the edge adjacent to the vent to perforations in the leather too near toget er.

portion of the foot that the object of assing the arms 8 of the match and register one with the other, per

mitting the'ready insertion of the flexible pin. In case the instant removal of the shoe is necessary all that is required is to seize the upper end or knob 7 of the lock ing-member which can be instantly withdrawn, allowing the vent to. instantly open as the shoe is withdrawn.

What I claim is: t 1. A molders shoe embracing in its construction a shoe bottom, a vamp, and a top joined to said vamp and upper and vented from its upper edge to the bottom and forming flaps lapping one inside of the other, a series of intermatching metallic loops whose ends are clenched through the i flap portions of the vent and whose intermediate portions are formed into eyes arranged to register with one another when the vent is closed, and a flexible pin adapted to be inserted and instantly removable from said registering eyes, substantially as described.

2. A moldel-s shoe embracing in its construction a bottom, a vamp and etc joined to the vamp and to the bottom an having a vent extending vertically from its u per edge to the bottom to form separablea s one of said flaps being overlapped inside the other, a series of metallic loops whose ends are clenched through the overlapping flap from the outside, and a cooperating series of metallic loops clenched through the opposite flap portion of the top so as to intermatch and register with the first mentioned metallic loops, and a flexible locking 1pin inserted through both sets of loops wien they are placed in registry with each other, substantially as described.

In witness whereof, I have subscribed the above specification. i
